Laminar film condensation on a horizontal wavy plate embedded in a porous medium

Investigation of vapor condensation on a flat plate and horizontal cryogenic tube using lattice Boltzmann method

“…4, the value of f −i (r F , t + Δt) following propagation step, which is equal tof −i ðr s ; tÞ following collision but prior to propagation step at time-level t, should be solved according to the given information in the surrounding fluid nodes, e. g.f i ðr F ; tÞ ,f i ðr ′ F ; tÞ , and f i ðr ″ F ; tÞ. Mei et al [16] provided the detailed formulation and analysis of the FH model. Applying a process of linear interpolation, the unknown value off −i ðr s ; tÞ ¼f −i ðr F ; t þ ΔtÞ can be formulated as: in which the fictitious equilibrium distribution function f i ⁎ has the form:…”

“…powerplants, heat exchangers and refrigeration, many effects on the film condensation have been addressed, including surface temperature [7][8][9], turbulent flow [10,11], wall suction [12][13][14] and others [15][16][17][18][19].…”

Thermal Transport in Metallic Porous Media

“…Similar extensive works or experimental studies of film condensation were performed extensively (Dhir & Lienhard, 1971;Popiel & Boguslawski, 1975;Sukhatme et al, 1990;Cheng & Tao, 1994). The use of porous structure for extensive surface of condensation was not a new idea and numerous related studies were found in open literature (Jain & Bankoff, 1964;Cheng & Chui, 1984;Masoud et al, 2000;Wang & Chen et al, 2003;Wang & Yang et al, 2003;Chang, 2008). Metallic foams possess a three-dimensional basic cell geometry of tetrakaidecahedron with specific surface area as high as 10 3 -10 4 m 2 ·m -3 .…”

An analytical investigation into the Nusselt number and entropy generation rate of film condensation on a horizontal plate

“…In practice, the condensate film cannot have exactly zero thickness at the plate edge. Chang [10,11] suggested that the critical condensate thickness could be derived by using the minimum mechanical energy principle presented by Bakhmeteff [12]:…”
